Peripheral Artery Disease (PAD) Treatment in Delhi, India

Peripheral Artery Disease (PAD) is a vascular condition in which the arteries, typically in the legs, become narrowed or blocked, usually due to the buildup of plaque. This restricts blood flow to the limbs, causing symptoms such as pain or cramping during walking, which often improve with rest. The condition most commonly develops due to atherosclerosis, a process in which fatty deposits accumulate on the walls of arteries.

PAD is a potentially progressive disease that can affect mobility and, in advanced cases, increase the risk of limb loss or cardiovascular complications. Early diagnosis and appropriate medical guidance can help manage the condition and improve quality of life.

Alternative Names of PAD

Peripheral Artery Disease is a form of Peripheral Vascular Disease (PVD), which refers broadly to conditions affecting blood vessels outside the heart and brain. Other related terms include:

• Arteriosclerosis Obliterans - PAD specifically caused by atherosclerosis
• Leg Artery Disease - descriptive, non-clinical term
• Claudication- a symptom of PAD, not a disease

Note: Not all these terms are medically equivalent; they refer to different aspects or presentations of PAD.

Who Is at High Risk of PAD?

Certain individuals have a higher likelihood of developing PAD due to lifestyle factors or medical conditions. High-risk groups include:

• People over 50 years old (risks can also occur earlier in individuals with diabetes, tobacco use, or familial vascular disease)
• Smokers or those with a history of tobacco use
• Individuals with diabetes
• Patients with high cholesterol or hypertension
• Obese or sedentary lifestyle individuals
• People with a family history of vascular or heart disease

Early screening is recommended for individuals in these risk categories to detect PAD before complications arise.

Types of Peripheral Artery Disease

The heart has four valves — aortic, mitral, tricuspid, and pulmonary — and each can be affected differently:

• Atherosclerotic PAD : The most common form, caused by plaque buildup in the arteries, gradually reduces blood flow, particularly to the lower limbs, resulting in pain and mobility issues.
• Non-Atherosclerotic PAD : Less common forms, such as Buerger’s Disease, Fibromuscular Dysplasia, Takayasu Arteritis, or arterial entrapment syndromes, occur due to inflammation, congenital abnormalities, or arterial compression rather than plaque accumulation.

Symptoms of Peripheral Artery Disease

PAD often develops gradually, and symptoms vary depending on the severity of arterial blockage. Some individuals may not notice symptoms until the disease is advanced. Common signs include:

• Leg pain or cramping while walking (claudication) that eases with rest
• Numbness or weakness in the legs
• Coldness in the lower leg or foot compared to the other side
• Sores or ulcers on toes, feet, or legs that heal slowly or not at all
• Weak or absent pulse in the legs or feet
• Erectile dysfunction in men may occur if aortoiliac arteries are affected (Leriche’s syndrome)

If left untreated, PAD can lead to serious complications, including tissue damage and gangrene.

Causes of Peripheral Artery Disease

The most common cause of PAD is atherosclerosis, where plaque composed of fat, cholesterol, and other substances narrows arteries, reducing blood flow. Other contributing factors include:

• Smoking and tobacco use, which damage the arteries
• High cholesterol, leading to fatty deposits in blood vessels.
• High blood pressure causes stress on arterial walls.
• Diabetes, which accelerates atherosclerosis and impairs circulation.
• Inflammation of blood vessels due to autoimmune conditions or infections
• Non-atherosclerotic vascular conditions, as mentioned above

Diagnosis / Tests for Peripheral Artery Disease (PAD)

Accurate diagnosis is essential to determine PAD severity and plan appropriate treatment. At Venkateshwar Hospitals, advanced diagnostic tools are available for comprehensive vascular evaluation. Common methods include:

• Physical Examination: Checking leg pulses, skin colour, and temperature changes
• Ankle-Brachial Index (ABI): Compares blood pressure in the ankle and arm to identify circulation problems
• Doppler Ultrasound: Uses sound waves to detect narrowed or blocked arteries.
• Angiography (CT, MR, or traditional): Provides detailed imaging of blood vessels
• Blood Tests: Assess risk factors such as cholesterol, blood sugar, and inflammatory markers (cannot directly diagnose PAD)

These tests enable doctors to evaluate the extent of arterial blockage and design a personalised treatment plan.

Treatment of Peripheral Artery Disease (PAD)

Treatment aims to relieve symptoms, improve mobility, and prevent complications such as a heart attack or stroke. The approach depends on disease severity.

1. Lifestyle Modifications

• Stop Smoking: Reduces the progression of plaque formation
• Adopt a Balanced Diet: Low in saturated fats and cholesterol.
• Exercise Regularly: Supervised walking programmes improve walking endurance and collateral circulation.

2. Medications

Doctors may prescribe:

• Blood thinners (antiplatelet drugs) to prevent clot formation
• Cholesterol-lowering drugs to reduce arterial plaque
• Blood pressure medications to control hypertension
• Cilostazol to improve walking distance in intermittent claudication (routine vasodilators are not generally recommended)

3. Minimally Invasive Procedures

• Angioplasty: Balloon dilatation to open upartery
• Stenting: A metal mesh tube keeps the artery open after balloon dilatation

4. Surgical Options

When repair is not possible, surgery may be required:

• Bypass Surgery: Creates an alternate route for blood flow using a graft
• Endarterectomy: Surgical removal of plaque from artery walls

5. Rehabilitation Programmes

• Structured walking and physiotherapy programmes improve stamina and leg function under medical supervision.

The Vascular Surgery Department at Venkateshwar Hospitals specialises in minimally invasive and surgical PAD treatments.

Complications of PAD

Untreated PAD can lead to serious complications, including:

• Critical Limb Ischaemia: Severe blockage reduces blood flow to the limbs, leading to gangrene
• Non-Healing Ulcers and Wounds: Risk of infection and tissue damage
• Increased Risk of Heart Attack or Stroke: Due to shared risk factors with coronary artery disease
• Amputation: In extreme cases, due to tissue death from insufficient blood supply

Regular monitoring, risk factor control, and timely intervention reduce these risks.

Prevention of PAD

Preventive measures focus on maintaining healthy arteries and reducing risk factors:

• Quit smoking and avoid all forms of tobacco
• Engage in regular exercise, particularly walking
• Follow a heart-healthy diet (low in saturated fats and cholesterol)
• Control blood pressure, cholesterol, and blood sugar with medical guidance
• Attend regular health check-ups if at high risk
